Definitions

  • This invention relates to a self-propelled screening apparatus according to the preamble of claim 1.
  • the invention seeks in particular to provide an improved self-propelled screening apparatus of the type referred to above, and which can be used to carry out screening operations while moving over the ground, and to discharge separated portions of the screened material to required deposition zones.
  • travelling hoppers to discharge material from the hoppers onto a prepared site e.g. during laying of hard core to form the base of a motorway carriageway, in which the hopper moves back and forward between a pair of side rails, and also moves progressively along each rail at the end of each path of movement, so that the prepared site becomes filled progressively with hard core.
  • US-A-5120433 discloses a self propelled pipeline padding apparatus.
  • the apparatus comprises a support frame and endless tracks for moving the apparatus over the ground.
  • An elevator transfers spoil from one end of the frame to a screening device located at the opposite end.
  • a discharge conveyor partially located below the screening device transports the fine portion of the spoil to a location remote from the padding apparatus.
  • US-A-5183160 discloses a pipeline padding machine for use with a motorised carrier (typically a flat bed truck).
  • the padding apparatus comprises a screen and a discharge conveyor located below the screen.
  • the discharge conveyor is for transporting the fine portion of spoil which passes through the screen to a discharge end located laterally of the carrier trailer.
  • the screening apparatus preferably has two modes so that unwanted material can be discharged to either side of the carrier, depending on the mode selected.
  • US-A-4861461 also discloses a self propelled pipeline padding machine.
  • the pipeline padding machine comprises a support frame, a moving means, a screening device located above the moving means, a hopper arranged to receive a supply of bulk material and to discharge the material to the screen, and a discharge conveyor.
  • the moving means comprise wheels located both below and remote from the screening device.
  • FR 733449 which shows the preamble of claim 1, describes a self propelled screening apparatus comprising a frame having continuos tracks and screening device supported by the frame above the tracks.
  • the screening device is adapted to discharge material to discharge conveyors which inturn discharge the material to a paint remote from the rear and sides of the frame.
  • a self-propelled screening apparatus which comprises:
  • the invention therefore provides a self-propelled screening apparatus or plant which is capable of receiving a supply of screenable material, separating the material e.g. into at least two size ranges of which preferably one includes so-called "fines", and discharging at least one of the separated range of screened material to a required deposition zone along which the apparatus is moved via said moving means.
  • the discharge means comprises a discharge conveyor arranged to receive said one separated range of material from the screen, and to convey the material outwardly of the frame of the apparatus.
  • the conveyor may be adjustably mounted on the frame, so that the discharge end of the conveyor can be adjusted laterally and / or upwardly and downwardly to vary its position relative to the frame.
  • the conveyor may be mounted to slew about an upright axis which is a substantially vertical axis when the apparatus is on level ground to adjust itself laterally, and about a substantially horizontal axis to vary the discharge height of the end of the conveyor.
  • the conveyor is mounted at one end of the frame of the apparatus, and the driver's cab may be mounted at the opposite end, and with the hopper and screen arranged between them.
  • the moving means may comprise any suitable form of driven ground-engaging members, but a preferred arrangement comprises a pair of endless tracks, which is a particularly advantageous way to carry out lateral adjustment of the discharge end of the conveyor.
  • the apparatus may be used to screen and then distribute screened material, while on the move, in many different operating environments e.g. in the laying of hard core on a building site, or the sub-base of a roadway, or in laying "fines" to fill pipeline trenches after the pipelines have been laid.
  • the screen which is mounted in the apparatus may take any suitable design, and may comprise one or more screen deck, and preferably with means to apply vibration energy to the screen deck(s) to improve the screening operation.
  • a slew ring type of mounting platform may be provided which pivotally mounts the superstructure on a base frame on which the endless tracks are mounted.
  • mobile screening apparatus which is designated generally by reference 10, and which is a self-propelled apparatus comprising a support frame 11, a screen designated generally by reference 12 mounted on support frame 11, a hopper 13 for receiving a supply of screenable material and for feeding such material to the screen 12 so as to be separated out into screened portions of different size ranges, means for discharging the separated portions from the apparatus, and taking the form of a discharge conveyor designated generally by reference 14, and moving means in the form of a pair of endless tracks 15 which support the frame 11 and are operable to move the apparatus 10 over the ground.
  • the screen 12 may take any suitable form, and preferably comprises at least one screen deck, and the entire screen 12 may be mounted on the upper end of frame 11 via suitable flexible linkages 16, and provided with suitable means to apply vibrational energy to the screen 12 in order to assist the screening process.
  • the screen(s) 12 extends generally perpendicular to the longitudinal axis of the apparatus (and of the endless tracks) and therefore oversize material which does not pass through the screens can be discharged laterally of the endless tracks and therefore will not obstruct the movement of the apparatus.
  • Screen 12 can separate the screenable material into at least two size ranges of screened material e.g. to produce so-called "fines" which are separated from larger material which may be disposed of separately for other uses.
  • the discharge means in the form of discharge conveyor 14, is mounted at the front end of frame 11 and is operable to discharge at least one of the separated range of screened material e.g. the "fines" along a required deposition zone while the apparatus 10 is being moved by the endless tracks 15.
  • the discharge conveyor 14 projects from the frame 11, when in the operative position shown in Figure 1, and conveys the screened material outwardly of the frame of the apparatus, for discharge to required locations.
  • the conveyor 14 may be arranged to be pivotally adjustable with respect to the frame 11 about a substantially vertical axis (by suitable mounting means not shown in detail in Figures 1 to 4), so that it can be slewed to carry out lateral adjustment, and is also capable of being adjusted upwardly and downwardly about a substantially horizontal axis in order to vary the discharge height of the discharge end of the conveyor 14.
  • Figure 3 shows an inwardly folded position of a discharge end portion 14a of the conveyor 14, which it may take-up when the apparatus is inoperative.
  • the discharge conveyor 14 is mounted at the front end of the frame 11, and the driver's cab 17 may be mounted at the opposite end, and giving a field of view to the driver through the space 18 (see Figure 2) defined below the screen 12, so that the discharge operation for the fines via the discharge conveyor 14 can be watched. This also assists in the adjustment of the discharge conveyor 14, as well as assisting the driver to follow a required path of movement.
  • the apparatus 10 may be used to screen and then distribute screened material, while on the move, in many different environments.
  • it may be used to lay hard core on a building site, or to form the base of a roadway.
  • it may be used to lay "fines" to fill pipeline trenches after the pipelines have been laid.
  • the discharge conveyor 14 may project from the frame 11 generally in the direction of movement of the apparatus, whereas in other situations it may be desirable for it to project generally perpendicular to the path of movement, so that screened material can be deposited to one side of the apparatus.
  • the apparatus may be arranged so as to be capable of remote operation e.g. via an umbilical, or a remote control arrangement such as an infra red transmitter control device.
  • FIG. 5 this shows a slew ring mounting which is a preferred additional component, to provide additional, or alternative means for lateral adjustment of the conveyor relative to the endless tracks (and also of the hopper / screens and the main superstructure of the apparatus).
  • the slew ring is shown by reference 18, and this pivotally mounts the main superstructure 19 on a base frame 20 on which the endless tracks 15 are mounted.
